Our SenSafe® John's Copper water quality test strips combine a wide range of detection of free copper in water with no interference from Iron and can be used in water with a wide range of pH. These water quality test strips are safe and easy to use for fast accurate results within the ranges of 0 to 2 ppm (mg/L), which permits the measurement of typical copper levels found in well, tap, pool, and stream water. The unique, patented, SenSafe® strip allows for low level detection without sacrificing accuracy.
This test detects Copper (Cu+1 & Cu+2). Copper is not typically found in city tap water. The major source of Copper in drinking water is corrosion of household pipes, fixtures, and faucets. Blue-green stains on plumbing fixtures, sinks, and bath tubs may indicate Copper is present. If Copper is detected in older plumbing, a test for Lead should also be conducted. EPA limit for Copper is 1.3ppm.
